I've found a box with 2 x 8" floppy drives. . . . external to some unknown computer. The box is a Panasonic JB3038P and inside are 2 X JA751 drives. The drive connectors and the cable coming out of the box are all 50 pin, exactly like an internal SCSI cable. Unfortunately it isn't recognised by a SCSI controller, at least not without fiddling with parity and stuff like that. Does anyone know what this might have been for? SCSI 8" floppy drives would have been great cos I don't think I'm ever going to find a compaticard ! Hans

PS Pinout needed

by af-list＠is1.wfi-inc.com

Hi, Someone a while back was going to check out the PS pinout for an HP Windows Client 425SX, but I lost the original message to remember who... Does anyone have it handy? The scratched sticker on the back looks like it says 20V~, but it's pretty scratched. The connector is 4 prongs in a row... Thanks, Aaron

Argh!!! PDP-8/m Memory

by healyzh＠aracnet.com

Well, with the aid of the "PDP-8/e Simulator" for the Mac, I figured out how to use the front panel, and execute the "Initial Operating Check". Load it into the real PDP-8/m, and start it. Wait a minute, that's not what it's supposed to be doing... After a bunch of investigating, and going back to the "PDP-8/e Simulator" to figure out how to display the contents of memory, I discover that there is nothing in memory :^( Based on the fact I can see what I'm trying to enter when I've got the switch set to 'MD' and hit Deposit, it sounds to me, suspiciously like I've got a bad 4K Core set. Anyone have any suggestions on something to check? Zane | Zane H.

More free (not quite classic) stuff...

by af-list＠is1.wfi-inc.com

Sorry to keep deluging the list with modernish freebies, but I figured there might be a few list people interested... Does anyone want a 486SX/33 base in a small box? It's actually the bottom half of an HP Scanjet 4si (so, same form factor as an HP IIP scanner). It's got 2 ISA/1 VLB slots...just perfect for a nice, small LRP router... (I'm using an identical one for that at home) Aaron

I just came into ownership (well, I've have it a couple of days) of a Supermac Technology Enhance card that was an internal upgrade for a Mac128K. I need some information on this card, such as feature set, connectors, etc. Basically I need a manual, a copy of same, or to communicate with someone with experience with this vintage card and a Mac 128K. Anybody know about it? Thanks, John jlewczyk(a)his.com

Semi-OT: Running CAT5 Cables

by CLASSICCMP＠trailing-edge.com

>Probably should make one thing clear here, as long as it's just the one room >and the garage, I plan on simply running one cable and connecting a hub in >the house to a hub in the garage.

IBM 5120 power question

by ss＠allegro.com

Hi, I just received an IBM 5120, from Germany. The back says 200/210/220 volts at 50 Hz. However, opening it up and looking at the power supply reveals enough choices in wiring that I suspect the power supply might already be capable of being easily adapted to 110/60 Hz ... does anyone have any familiarity with this system? Otherwise, I'll be visiting Fry's for something (transformer?). thanks, Stan Sieler sieler(a)allegro.com Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler

New Collector in Need of Help!

by dylanb＠sympatico.ca

Did you ever pick up the Univac? -----Original Message----- From: Owen Robertson <mrdos(a)swbell.net> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Wednesday, November 03, 1999 11:06 PM Subject: New Collector in Need of Help! I am kind of new to the collecting game. I am in need of some help. I need someone to tell me where I can find older and larger computers. I have a lot of micros, but now I am looking for bigger game. I have decided to focus my collection on older mainframes and minicomputers. Can anyone point me to sources? I found a local business that has older and larger computers, but the owner and I didn't hit it off. It's really a shame. He had some great stuff. While I was there I had to watch the workers scrap what looked like a very old classic control panel. Also, someone recently offered me a UNIVAC System 80. Anyone know anything about it? Is it something worth having in a collection?

Old plasma display

by truthanl＠oclc.org

I have data sheets on Sharp ( electronics corporation ) LCD units circa 1988. They Show a LM64015T Display which was also 640 X 400. Its logic was 5.0 V (MAX 6 V) and the Supply (LCD) drive is Typical -21V (Min- 32V. Max -14V) It was driven with a Yamaha V6366 display controller. There is also a TDK CXA-1301 Inverter spec'd which provides CCFT backlight voltage ( Typical 1000 Vrms @ 400hz) The Sharp LM64015T display is a 12 pin device, Pin 1 labelled S for Scan Start up high Pin 2 CP1 (clock pulse 1) Input Data latch (High to low) Pin 3 CP2 Data Input Clock Signal ( High to low) Pin 4 open Pin 5 NC Pin 6 Power supply for Logic Pin 7 Gnd potential Pin 8 Power for LCD Drive with pins 9-12 being display Data, D0 - D4 respectively - (High on)(Low off) This gives an Idea of typical voltages and interfaces of the era. This may not apply to the Specific Matsushita device you asked about. It points out that there are often Display Controllers Like Yamaha V6366 and High Voltage inverters like TDK CXA -1301 ( 100V- 1000V) for backlighting.

Tandy 2000

by leucoplast＠seanet.com

I'm also having the same problem on my 2000. I have a feeling that it's the floppy controller chip(s) but I'm not sure yet. At first I thought it was a bad power connector but they all check out OK. Then I replaced the FDs with no change. I even replaced the motherboard with a spare that I had but all that ever comes up is the "256k memory" line, and that's all. Still, I'm only making guess' here. I should say that I aquired my two machines, one with a hard drive, for free but they were not tested. I had to have a video cable made before I could see what was going on with the system, so I'm not entirely sure of what is supposed to happen on bootup. I had the same problem with a Tandy HX a while back, and that turned out to be a bad memory chip that was locking up the system when it ran it's memory test. I've been tinkering with my 2000 off and on as I get new solution ideas but so far, I'm stuck too.

Tampa Hamfest

by rigdonj＠intellistar.net

I just got back from the Tampa hamfest. Besides all the odds and ends, I picked up a HP 9845 claculator, three old HP 2623 terminals, two HP 9885 8" disk drives, a HP 9878 system expansion box and 6 or 7 interfaces for the 9845. Some of the intefaces are brand new and haven't even been unwrapped. Also picked up a HP 7245 Thermal Plotter. A very strange item! It prints on thermal roll paper using a full width printhead but it does excellant printing and plotting. Other items of interest include a HeathKit ET-3100 digital trainer with manual, three IBM computer technical reference manuals (IBM convertable Vol I and II and PS/2 model 30) and a Tektronix 178 linear IC tester. I also found another manual for my Tektronix 4051 computer. This one covers the hardware for the disk drives. Also got some kind of I/O box for the 4051, I don't know exactly what it is yet. Also got four new manuals for a Tektronix digital trainer. I left behind a FREE & operable PDP 11/34 with expansion cabinet. I'm not real interested in DEC stuff and I didn't have room to haul it or to store it. I barely missed getting a very clean HP 45 calculator in the box with charger for $5. But a close friend of mine that's also a big HP fan got it so I'm not too upset. All in all, a pretty good hamfest! Joe

PDP-8/m !!!!

by healyzh＠aracnet.com

I finally have a PDP-8/m. On the 1st of November someone that knows I'm looking for one notified me of a Internet auction that was ending in about 4 hours, and I was able to get the winning bid of $356 in (thankfully this wasn't on eBay). M8330 -- Timing board (system clock) M8310 \_ KK8E CPU control M8300 / KK8E CPU registers M847 -- MI8E Hardware Bootstrap Loader. M848 -- KP8E Power fail and auto-restart. M849 -- shield to isolate memory from CPU M8650 -- KL8E RS232 or current loop serial interface. G104 \ H220 > MM8E 4K memory (H220) G227 / M8320 -- KK8E Bus terminator It arrived today, and I just unboxed it a few minutes ago. As a result you can see the web page with pictures at the following URL: http://zane.brouhaha.com/healyzh/PDP8m.html Now, I've got to figure out where I'm going to put it for the time being. I also need to figure out what a couple of the cables that were included are for. Unfortunatly I think the console interface is a 20ma interface. However, there is a Canon plug that I've no idea what it goes to. I'll be cleaning it up before I try and fire it up. Unfortunatly I've got to leave for work in a little over an hour so that will have to wait till tomorrow. Also, the module list that I announced yesterday has grown in size considerably and now includes at least a few parts from the following systems: PDP-4 PDP-5 PDP-6 PDP-7 PDP-8 PDP-9 PDP-10 PDP-12 PDP-14 Programmable Controller PDP-15 PDP-16 The YADML can be found at ftp://zane.brouhaha.com/pub/ModuleList.txt Zane | Zane H.

PDP-11 Freeware CD's under emulators

by CLASSICCMP＠trailing-edge.com

Zane wrote: >Of course it would be nice to mount the RT-11 Hobbyist software CD on a >emulator running the Hobbyist RT-11, and without MSCP, I don't believe that >is possible. The best way to do this is with John Wilson's full E11, where you can directly mount the high (RT-11 disk structure) partitions of the CD-ROM. Of course, this requires the commercial version of E11 for large disk MSCP support, and also requires a regular (non-hobbyist) RT-11 license to run (as the hobbyist RT-11 license is only good on the Supnik emulator.) I think it also requires a SCSI CD-ROM (though I could be wrong and it'll work fine with an IDE CD-ROM.) The next best way to do this is free, and doesn't require commercial anything, just the Supnik emulator running on your system and a copy of RT-11 in compliance with the hobbyist license. If you look in the RT-11 freeware CD at the ISO9660 partition, you'll see that each and every piece of software on the CD is represented as a logical .DSK file. In particular, in the /dsk directory, you'll find 185 logical disks of freeware, split up between the SIGtapes, the DECUS 11-xxx entries, and the "other" stuff. These can be mounted as any sort of volume you like under the Supnik emulator, as long as the emulated device is large enough to hold the contents of the .DSK (i.e. you can use an emulated RL02 to hold any virtual .DSK up to 20480 block.) Then you're home free, and have "direct" access under the emulator to all the contents. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

I helped Bob Supnik debug the RP driver for his PDP-11 emulator (because 2.9BSD didn't used to install) and can say that I'm happy with it. My BSD images are from a *real* 2.9BSD 16MT9 that I got about 15 years ago, and, once the RP driver was fixed up, things worked real smooth.

Between Project 64 and the Funet.Fi Commodore archive I think the 64 is probably one of the best documented 8-bits on the net (and some of the other Commodore 8-bit models as well).

(from usenet) PDP-11 emulator available

by mbg＠world.std.com

>"Bob Supnik's is quite excellent with better support >from the looks of things" Bob's emulator is quite good, but a drawback is that it doesn't have MSCP emulation or Ethernet emulation. E11 (Ersatz-11) has both. I believe that Viking does as well. I don't know about Charon... >What is the status now of Bob's work, now that he has left DEC? >I thought I heard that Megan was working on 10 support, for example. Me? 10 Support? No... I'm simply working on trying to get my KS10 operational, while working off and on on a pdp-10 emulator, using Bob's package as a base. I have been working toward a KA10 emulator with conditionals (where I understand things enough) to do the right thing for a pdp-6 or a KI, and for those instructions I have done, I'm getting almost 600k emulated instructions per second (eips?). But I don't have the PI system working at all, and there are some issues about instruction processing I don't have down yet... Daniel Seagraves is working on a KL emulator, and actually has some code running, it appears (at least he has tried to boot ITS and it has done a little of the boot process). There are some other efforts around the net to produce various -10 emulations... I'm also in the process of getting all the software I do have for the 10, currently on tapes, off to other storage with the help of Tim Shoppa (actually, I'm just supplying him with tapes, and he's doing the work... :-) Most recent mail from him indicates we appear to have almost a complete 7.03 distribution, parts of the 7.03A patchs and working on a 7.04 distribution. But as for 'supporting' this stuff... I was an okay -10 programmer in college... I mostly did -11 stuff. I'll never be anywhere near the level of the -10 gurus who wrote this code... so I would not presume to 'support' it. Isn't XKL doing -10 support?

DEC and misc stuff available

by cfandt＠netsync.net

Here is a list of DEC gear I must get rid of. It's a sizeable part remaining of that Great Haul I had back in Summer '98. Setting out in our garage. Also, some miscellaneous items are listed at end. Absolutely no room to keep the machines as I must soon clear out a storage cubicle upon which I'm paying $62/month rent. I could certainly better use those bucks for paying bills and also want my radio items stored at home. Can't contact anymore -nor find thru searching to the best of my ability- the previous party who was interested. So it goes to the list. Come an' get it!: ** VAX 11/750 with a TU78 console tape cartridge (diagnostics? boot?) Was mainline system at the place I got all this gear from. Office had been closed since 1994 and equipment stored there. Owner decided to not renew his lease and had to get rid of everything fast (in the meantime, I discovered this and bought a truckload of goodies :-) Reportedly has VMS 5.3 or 5.4 plus several diff. language compilers on the RA81's listed next. Set of six TU78 cartidges with VMS 5.3 on them. ** RA81 in 40" rack (p/o the 750). ** TU80 tape with RA81 drive in 40" rack (p/o the 750). ** PDP-11/24 w/FPF11 (M8188) floating pt. option, two RL02's all in 40" cabinet. Cabinet is same physical size as the 750's cabinet (40" high, about same width & depth.) Console prompt okay but need to fix RL02 problem. ** PDP-11/34A in a 40" rack. Not complete. Old, early style, square-edged shaped metal programmer's panel. Not the stylized plastic shape most are. ** RL02, at least three units *not* including the two in the 11/24. Fault lights appear on two or three (yes, I checked them while hanging off my 11/34A with RL controller :-) ** RL01, one unit. Fault light, IIRC. ** RK07's, four units. One is known to come up without a fault. Another has rather noisy spindle bearing. Others Fault, IIRC. ** RK611 system unit for BA11 with all five boards. Came out of the 11/34A I'm keeping. ** RA60 (needs to be fixed) Seems to be a platter motor driver problem. No spin-up, IIRC. Two disk pacs included. Note: I strongly suspect this RA60 went with my 11/34A, which I'm keeping, as the box had the UDA50 boardset installed and of which was up and running next to the 11/750 at the ex-owners' office. So, probably 11/34A-specific software on the pacs. It's RSX-11 v. 4.2 or 4.3 I rather suspect. *Think* I have an extra UDA50 boardset boxed up somewhere. There's a set in the 11/24 I know. Then again, it could have hung off the /24 as it, the RA60 and the /34A were all setting near the 750. Rest of the stuff on this list, except for two RK07s, were crammed into a small storeroom up the hall. ** decwriter I (LA180) page printer. Not checked. ** decwriter II (LA36) printing console. Not checked. ** decwriter III (LA120) (Typical printing console device for the 11/750, et al). Not checked. (BTW: What's the exact differences between the decwriter II and decwriter III ??? I've got no documentation on them.) ** ADM-11 terminals, two units. Not checked (as of yet). ** VT100 terminals & kbds. Two or three units. Working fairly well IIRC. ** DECmagtape system. TS03 drive and TMB11 I/F (together called a TMB11-M system). Mounted in a DEC 6' tall PDP rack (with the purple and magenta trimpiece at the top). TMB11 I/F mounted in a 10.5" BA11 box. Not checked. Has two of the three RL02's mentioned above residing in the rack. Uses 7" dia. tape reels mentioned next. ** tapes 7" size, 800 BPI, about 85 of them ** 7' tall tape storage rack for hanging above tapes. ** RK07 disk pacs, about 20 or so. ** RL01 disk pacs, about 20 or so. Have to sort out some to keep on hand for an RL01 I'm keeping. ** RL02 disk pacs, about 25-30 or so. Same, have to select-out some for one or two RL02s I'm keeping. Here's something from my collection which *must* go because of severe space limitations: ** Tektronix 4015-1 graphics terminal, two units, same as 4014 except includes APL keyboard and 19" screen. I've had these in the collection for 14+ years and they still worked when last checked in '97. RS232 communications. Came out of the old IBM Endicott plant in '84/'85 when they "downsized" (jeeeze, I dislike that word now since I had personally experienced it last year :( ) Kinda big. ** Zenith Z19 terminals, two or three. One I know has defective RS232 chips, other(s) are okay. ** Zenith Z90. Carterphone OEM version. Some additional boards and parts go with it too. Worked, no floppy installed. ** Teletype ASR33 (one or more units). One or more may function. Need relubing/adjustment. ** Bunches of Zenith Z150-series boxen and keyboards. 15 sets I think, in various conditions. I might dredge up some more smaller stuff to toss onto this listing as time allows. There's certainly more to go. I'm waffling on getting rid of my VAX 11/730 which needs mass storage of some sort added and some other minor restoration. It's a small big iron VAX which makes me unsure whether to get rid of it so far. If ya want to contribute a little $$ on top of shipping/packing material costs I sure won't complain! :-) Smaller items could be shipped but the big stuff should be picked up (unless you're prepared to pay the freight costs for it). Phone: 1.716.488.1722 from 08:00 to 20:30 EST. Location: Western NY State, off the NYS Rt 17(very soon to be I-86), just past West side of Jamestown on Rt. 394. Thanks for your interest. Please take it away soon!

keyboard keys

by lemay＠cs.umn.edu

I'm restoring a TRS-80 model 1, 16K level II basic, cassette tape version (though I dont have a cassette tape player yet, just lots of tape software). Anyways, every key seems to have keybounce problems. These keys are the kind with a rectangular tube which, when depressed, allows two contacts (one flat and one with about 4 prongs) to come into contact with each other. There is a strange mustard-like substance in each key in various places near the contacts. I'm wondering if this yellow stuff is supposed to be there, ie, is it some sort of conductive rust preventative? Is it supposed to be the color of old mustard, or has it seriously decayed in the past 21+ years? Suggestions on how to properly clean/refurbish this to near-new condition would be appreciated. -Lawrence LeMay

Well, for those of us who cant have our own 11/34s, here's hte next best thing: Path: news.onr.com!news-out.cwix.com!newsfeed.cwix.com!newsfeed.tli.de !do.de.uu.net!f.de.uu.net!news.uni-stuttgart.de!news.ruhr-uni-bochum.de!gmd.de !gmdtub!not-for-mail From: Hartmut Brandt <brandt(a)fokus.gmd.de> Newsgroups: alt.sys.pdp11 Subject: Version 2.4 of the p11 PDP-11 emulator Date: 19 Nov 1999 15:04:33 GMT Organization: GMD-FIRST Lines: 49 Message-ID: <813ou1$lp7$1(a)freebsd.first.gmd.de> NNTP-Posting-Host: scotty.fokus.gmd.de User-Agent: tin/pre-1.4-19990805 ("Preacher Man") (UNIX) (FreeBSD/4.0-CURRENT (i386)) Xref: news.onr.com alt.sys.pdp11:644 Version 2.4 of p11 - the Begemot PDP-11 emulator - is available on ftp.fokus.gmd.de:/pub/cats/usr/harti/p11. This release supports the following platforms: FreeBSD 4.0 Sparc-Solaris 2.[5678] Redhat-Linux It will possibly work on FreeBSD [23].* and other Linux variants. To build it you need libbegemot (avalaible in the same location), gcc and gmake. Previous versions also built on BSD/OS and SunOS. A version of the emulator is run on one of our machines. Try one of the following (it may not always be available): telnet scotty.fokus.gmd.de 10000 telnet scotty.fokus.gmd.de 10001 telnet scotty.fokus.gmd.de 10002 telnet scotty.fokus.gmd.de 10003 to get connected to one of the four available terminals. If telnet connects, but this terminal is currently in use, you'll get a short message. You should then try connecting to another port. Once you are online, log into 2.11BSD with username and password guest/guest1. Don't forget to logout, before disconnecting with telnet. Note, that there is an IP connection to the host machine, but not to the outside world (this is due to IP routing restrictions in out network). The current implementation emulates a KDJ11A, one or more RLV12, RHV??, RK11 disk controllers, a boot ROM, one or more KL11A controllers, on FreeBSD and Linux a DEQNA ethernet adapter, a read-only TM11 tape and a standard line printer interface. A boot ROM (with source code) to boot from RL/RK and RP discs is included. On a 450MHz Pentium-III a full 'make world install' of 2.11BSD takes around 6 hours, which is several times faster than a real PDP. Floating point performance is even higher. The emulator hast tested with 2.11BSD, RSX and RSX-PLUS, RT V4, V[4567]-Unix and XXDP. Enjoy, Harti B.

Classic Hardware Documentation Project

by edick＠idcomm.com

It seems to me that there are cases such as government funded privately (by contract) generated documents in which ownership of the information is public, but ownership of the document itself, i.e. the layout, text formatting, etc, is property of the party or parties who generate and print it. In the case of hardware, the information is part of a patent, not part of the document in which it is presented, therefore subject to prevailing patent law not copyright. This, like most legal matters, is probably subject to the whim of whatever court your adversary manages to get to hear the matter if you don't beat him to the punch, however, until such time as superior court decisions etch it in firmer material.

a little more info (was: going soon...)

by yakowenk＠cs.unc.edu

I've now got a little more info about those machines in Woodbridge VA. Here is an excerpt from the e-mail: > If you have one or two people that are serious about this, that would be ok, > but maybe not a dozen.... I looked around a bit on Friday and the DEC is a > PDP 11/34, there are several old IBM (and other ) pc's, printers (atleast 2 > NEC spinwriters and other Oki, epson and Lord knows what else) and boxes & > boxes of old software. Boxes of old boards.... just a plethora of fun, sorta > like going thru Grammas attic... Unfortunately, it sounds like mostly PC stuff. And he does not want to deal with a dozen different people. So, I'd like to choose two designated information-collectors to meet at the warehouse (or factory, or whatever it is) and make a list of what's there. If these things are really going for free, we'll want to work out a way of avoiding conflicts, so nobody feels cheated. I suggested that this guy may want to take offers as a way of resolving it, but I don't know if he'll do that. If he does, I recommend bidding _low_, since he wasn't planning to make money out of this. I expect he will choose a date in the first weekend of December for viewing the heap. (He will be out of town this weekend.) If you want to volunteer to be on the info-collection team, let me know. If I get more than two, I'll choose by rolling dice. If a chosen person has to back out, I'll roll the dice again. Also, after this, I will be sending only to the list of people who have expressed an interest, not to the entire classiccmp list. If you want to be kept informed, and are seeing this only through the classiccmp mailing list, you need to let me know to add you to my own list of interested people. Cheers, Bill.

Supnik simulator for PDP11 mods (Was RE: PDP-11 emulator available)

by classiccmp＠mrynet.com

The recent interest for simulators/emulators on this list has prompted me to share publically the modifications I've made to the Supnik 2.3d simulator. It is available at: ftp://ftp.mrynet.com/pub/operatingsystems/simulators/sim2.3d+BB1.tar.gz Others who have already seen the modified work from me will have known this file as "sim2.3e.tar.gz." I've changed the distribution file name to prevent confusion with any official distribution that might perhaps follow from Mr. Supnik. There are regular (daily) minor changes to this as I clean it up and verify portability to other platforms. My interest in making modifications were for the same reason I've seen posted about the Supnik emulator: limited serial line support. Below is a summary of my work. Please email me any impressions, suggestions, requests and additional modifications. Kudos to Mr. Supnik for his extremely understandable and workable simulator. Cheers, -skots --------From the top-level README-------- From: Scott G. Taylor September 4, 1999. This is the Supnik Emulator for the Nova, IBM 1401 and DEC PDP 8, 11, and the 18b family PDPs 1, 4, 5, 7, 9 and 15. A directory exists for each of the models where an executable is created. (Except for the PDP 1, all the 18b CPUs are handled by the pdp18b executable coding). Current copyright information is contained in the file COPYRIGHT. The original copyright and documentation are contained in the file 'doc/simh_doc.txt'. Additions to the original Supnik 2.3d distribution: A utility program called `xtapeutil' has been added to the utils/ directory. This program allows you to interactively read and write tape images in the format used by the emulator. You can create tapes from individual files, or from "tape log" mapped images. The generated images have been tested extensively and found to work with all bootable tapes for RSX, RSTS and UNIX operating systems. It is also currently being reworked to aide in transferring real-tape data to simulator-format images, as well as handling labelled real- and simulated-tapes. Summary of modifications: The only modifications to the original source code are in the PDP-11 simulator version. With the exception of reorganisation of code into discrete directories for each simulated processor version, no other code has been modified. The only exception is a small modification to allow adjustment of the CLK timing in simulators which utilise a clock (in common/scp.c). Additionally, a structure of makefiles, compatible with BSD and GNU make, has been added to facilitate simulator builds. The PDP-11 code was modified in the following ways: o Addition of a 4-line DL-11 driver (pdp11_dl.c). o Removal of the stddev KL11 code. The console KL11 functionality has been assumed by the pdp11_dl.c DL11 code. The console line, however, can be reimplemented by defining -DUSEKL in the pdp11 Makefile. o Work-In-Progress on a 4/8-line DZ-11 driver. o A utility program, called 'netline' has been created to allow the simulated DL-11 serial lines to be accessible via TCP TELNET protocol. See README_pdp11 for more details. Building the simulators:

Old plasma display

by stefan.boss＠gmx.net

Hello I have an old Matsushita plasma displays (from a Compaq PC I think). Do you have any information about this (or a similar) display... any datasheets about data communication or the power connector pins??? The display has the numbers MD400F640PD5 7.0.13 C:60963 I'm very glad if you could help me... yours sincerely, Stefan PS: I'm a student from Switzerland and I might be interessted to write a assembler-program with my microcontroller system (MC68HC11G5) for the display.

Even Bigger problem with VMS

by M.Malik＠roehampton.ac.uk

Hi, I have an old Vax 4100a/VMS 6.2 machine and have tried what was suggested here: http://www.heydon.org/kevan/mlists/classiccmp/1997- 07/msg00447.html The problem I have is that the system disk is full (probably due to log files) and I am unable to boot up because of this. It does not work even with minium boot, I just want to be able to boot to the system disk and to delete/purge some files to get the system back up again. Can anyone help? Thanks in advance. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Mubasher Malik Snr Systems Engineer C&IT (M.I.S Team) Roehampton Institute London Tel: 00 44 (0)208 392 3122 Fax: 00 44 (0)208 392 3182 e-mail: M.Malik(a)roehampton.ac.uk ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Copyright clearance (was Re: Classic Hardware DocumentationProject)

by edick＠idcomm.com

It can go either way. The information itself is likely to be property of the US Gov if it, and the hardware to which it pertains, was developed under U.S. contract. Nonetheless, unless the manual was actually printed by the GOV it may be copyrighted by the developer of the manual. You have to look at the copyright declaration in the document. With hardware documentation which was freely and customarily given away, e.g. separately from the hardware itself, like the OEM manual for a floppy drive, it's unlikely the copyright can be claimed to be of any substantial value. The owner of the copyright can probably cause you to stop publishing, posting, and distributing it, but since it was never sold, violating the owner's copyright cannot be interpreted as substantial damage to the owner, hence no basis for judgment for damages exists. Another thing is that if you publish the information in a format different from that in which it was published, i.e. flowed around the embedded illustrations in a different way, though it damages the value by fouling up references to the figures, it makes your document not necessarily the one which was copyrighted to the owner. It just depends on how useful the resulting document is. I don't know how helpful it is to know these things, but it's always useful to remember that nothing's etched in concrete where courts, judges, and lawyers are involved. Everything's subject to interpretation. It's just hard to imagine a court awarding damages to the holder of a copyright on a document pertaining to, and only to, a specific piece of hardware, the owner of which is the one party to whom that information is of interest, since it was for his benefit that the information existed in the first place, and it was generated to support the sale of that hardware, which purpose was clearly fulfilled at some time in the past.

Classic Hardware Documentation Project

by edick＠idcomm.com

I don't know what the "ideal" format for storing complete documents with both text and graphic representations of their content. I also don't want to resurrect the virtual war that resulted when I previously offered to generate PDF formatted files from dozens of floppy and hard disk documents in my possession. My scanner likes to produce TIF files and I can send 'em to you that way or in any other format that's hopefully easier to ship. Emanuel Stiebler was kind enough to scan the SHUGART and SEAGATE documents I have. His OCR software, which, in the wake of the flame-war over format, he hasn't yet found time to apply, prefers 4-bit greyscale for the best conversion. Mine prefers single-bit, which is naturally a quarter the size, so since mine produces typically 1 MB/page, his produced considerably more than that, and when he brought his 8GB SCSI drive for me to copy those files, I had to lay it off to tape because I didn't have that much space on my server. That documentation comprises perhaps half of one percent of what I'd like to put out there, but I absolutely don't want to form and maintain a website, so I'm grateful that you're willing. In compressed PDF, you can probably host hudreds of documents. In PCX, which I agree is an icky format, but which is about 1/4 the size of the single-bit TIF files my scanner coughs up, you won't even be able to host half my Intel documents. OCR is a possiblity, but there's no realtively easy way to link converted text to the associated illustrations, which are plentiful among old hardware doc's, to say nothing of the text found within the illustrations. I'd say you've got a tough job ahead of you, and I'll be sure to let you know they're about to demolish one of those old stock-brokerage/insurance company buildings with a 750TB disk farm still in it. Nonetheless, if you come up with a way to solve this data format/transport problem, please share it with me.

Well, thanks to all those who replied last time. I think I may be getting somewhare with the vax. cant get the tape drive or deqna cards working, (their leds tell me something is wrong) but that is not what I am going to be asking about. When I try and boot the vax, I get Loading system software, 2..1..0.. %SYSBOOT-E-Unable to locate file DUDRIVER.EXE ?06 HLT INST PC = 0000692B now I can get into the sysboot utility, have no idea what to do here. Is there a way I can get around this missing file, is the some command at the chevrons (>>>) or the sysboot> that I can use to get round this? Thanks Benjamin -- www.carnagevisors.net

"One thing that might be cool is a list of doc's that people have available for *trade*." That might be one of the fields in the record, along with # of copies. Or, if people have web pages, just a centralized list of 'have' and 'wanted' links would be handy.

"I'm all for that. I fall into that latter as I've got a bunch of hardware without docs and have found none around so far. Then, I've got some docs but not the iron . . . " I think most folks are in the same situation, and I REALLY hate it when I find out Frank, Eric, or someone else out here has a manual that I just paid out the nose for on eBay. I'd be willing to host this on spies, if folks feel like sending me lists of docs or sw that they have for non-consumer computers (minis, etc. someone else can take care of the micros..) and a contact adr. I'll have to do this by hand for now until I can put some scripts together that would let people add/delete things through a web interface.

Just to let folks know on the list that don't know about it already, www.spies.com/aek/orphan.html is a collection of documentation from dead computer companies. Other scanned docs exist for companies that are still around, as well as pointers to other sites. It may make sense to start a list of documentation and software that exists in private collectors hands to avoid duplication of effort, as has already happened with PDP-8 doc scanning, and to help others who have the iron, but not the bits.

New toy (Fat Mac 512)

by DSEAGRAV＠toad.xkl.com

And that's just what the nameplate says, "FAT MAC 512". Came with a disk with version 4.1 of Finder (Unknown MacOS) Finder says it's by Bruce Horn and Steve Capps, (C) 1985 Apple Computer. The Mac itself has the keyboard, mouse, and a printer, and an external disk drive. Got it for $10 at a garage sale. This would make a perfect console for the PDP-11 if I can find a terminal program for it. ^_^ The machine is in beautiful condition. Not a scratch on it. I'm gonna try keeping it that way. ^_^ I was told by the seller it was a broken word processor, it just flashed a question when she turned it on. (The disk was jammed halfway in the drive. A quick application of car keys fixed that. ^_^ Didn't roach the drive either.) I may take pictures later. (ObSlashdot)Wonder what I could do with a Beowulf cluster of these... ^_^ -------

GREAT!!! I've been pondering where to stash the documents, which will ultimately amount to about 100GB of scanned , maybe 25 GB of PCX-formatted documents on disk drives, which will compress, of course, but the volume grows steadily as I muck out.

Xerox D-series workstations

by yoda＠isr.ist.utl.pt

I've just read your mails about the Xerox's keyboard/mouse interface, and it seems I've reached the same conclusions (cool!). Now, I'm still hacking a simple 422-232 interface, using the HandyBoard's MAX232 and some TTL logic. Although, I've been able to receive ASCII text from the bus. Can't send useful data still. (I can post the details of my connections if anyone interested). When the workstation boots, it sends a burst of data through the RS422 bus (in hex): 01 55 aa 00 01 02 03 ... fe ff 00 01 02 03 ... fe ff But I still can't get a repeatable behavior, I mean, when I press some keys, the xerox seems to react, but if I press the same keys again, it does not. I suspect It has to do with an improper 422-232 level conversion. I'm going to try again tonight.

YADML - Yet Another DEC Module List

by healyzh＠aracnet.com

What can I say, I got tired of 3+ different lists for modules not covered in the "Field Guide", and have merged them into one list. I've also added some flip-chips to the list that weren't in any of the other three lists. Currently it's primarily PDP-8 related, but I'm working on fixing that and adding stuff from other PDP's (I'm not adding stuff in the "Field Guide"). The original three lists can be found at: http://www.spiritone.com/~nabil/pdp8/modules.txt http://www.spiritone.com/~nabil/pdp8/omni.txt http://www.spiritone.com/~nabil/pdp8/sq.txt The merged list with addtions can be found at: ftp://zane.brouhaha.com/pub/ModuleList.txt If anyone has any additions or corrections I'll add them in. If anyone has any suggestions I'd be interested in those also. Zane | Zane H.

old NEC APC computer

by Innfogra＠aol.com

I had a color APC set up for AutoCAD 1.1 at one time. One of several that passed through my hands. They are a very nice machines, the color especially. There is a NEC hard drive (5 1/4" external) that worked with it. I had a hard drive and APC documentation until my warehouse cleanout. I don't think they were salvaged. If there is any software (CPM-86 and/or MS-DOS 2.11) for it the APC is a good candidate for a collection. Paxton

New finds and some h-11 help

by dogas＠leading.net

Hi all, I've been fortunate lately. Recent system arrivals include a Motorola Exorcisor&Disk and MEK 6800d2, an OSI Challenger iii and replacement power supply, an OSI Challenger 500 with a chunky doc set, a MITS 680, a KIM-4/hb tvt-6/etc...,and a Heathkit H-11/H-27. Frankly, I'm overwhelmed, but enjoying it. It's hard to find all the necessary time each of these machines are screaming for between all my other grand schemes but I manage. I've been pretty quite lately but lurking when I get a chance and as usual have enjoyed it all. I know there's alot on the h-11 in the archives and I'll hit them too but I know zilch about it right now. The cards in the tilt out qbus(?) are: 1. Digital M7264 2. H-11-5 Serial i/o 3. H27 Floppy i/o 4. H-11-5 Serial i/o 5. M8044 CB 6. M9400 YB 7. WHA-11-16 16k x 16k Memory First question, does it matter how these boards are plugged into the backplane? If so, where do they go? What are boards #6 and #7? The WHA-11-16 had a memory chip that was partially popped out and the right drive latch on the H-27 is cracked but repariable I think. Next question, anyone got a recommendation on where I can find that rectangular(4x6 pin) serial connector? And lastly, dc on, dc off... ??? I'd appreciate copys of any docs for this thing anyone is willing to copy (and software too...) My goal is to get rt(h)-11 and some decus? software (a c compiler) software humming. Thanks for any help - Mike: dogas(a)leading.net

I used to work on the TI 99/10 but I don't remember much about them. I do remember that it was nearly impossible to fix the circuit cards.

old NEC APC computer

by woodfrog＠operamail.com

Hi all, this is my first post to the list. I saw an old NEC computer in a storage shed that I was thinking of trying to save. It has 'APC' on the front (Advanced Personal Computer?), two vertical 8" floppies, and built in screen. Is it one of those 8-bit CP/M systems? If anyone has any info on this system I would appreciate it. Thanks. Andy ----------- Andy Molloy woodfrog(a)operamail.com

Whoohoo! Fortune Telling...

by dylanb＠sympatico.ca

No Duty. I move machines from the US to Canada and Canada to the US.. You pay DEPENDING on how honest you are. You may have to pay State tax on the purchase price when bringing it across the border. Be sure to say it is for your PERSONAL hobby. Get a receipt from the place you are purchasing the mini from. If you..,,, well.... ummm, some people.. might do this: Go to the customs office BEFORE they pick up their equipment. They bring a small dead case with a tag that has the "model # and serial number" of the mini. They get customs to give them a green card for the unit so it can re-enter the country free of charge. You get the idea.... or They write you a receipt for $50 calling it old computer junk.. It's hardly worth while if you are paying small $$$$ for it. Make sure you know the country of origin. If you tell customs this is a business transaction and you don't have an Import/Export License nor valid paper work you will probably end up LEAVING it there... (after they beat you up ;-) ) To avoid hassles I got my import/export license and am my own Broker... no headaches other than having to wait in line with the truckers. john http://www.pdp8.com/ -----Original Message----- From: Eric Smith <eric(a)brouhaha.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Saturday, November 13, 1999 4:57 PM Subject: Re: Whoohoo!

old NEC APC computer

by jeff.kaneko＠juno.com

According to the _Microcomputer_Buyers_Guide_ (1983 edition): "The APC is a new 16-bit microcomputer from NEC. The basic compact integrated desktop system includes the following components: NEC UPD 8086 (8086 compatible) 5MHz microprocessor, 128k RAM memory; 4Kb ROM; 4kb CMOS RAM; parallel printer interface; one or two 8" floppy disk drives at 243Kb or 1Mb capacity; music output; momochrome or color display (depending on the model); and keyboard. The APC can expand to 256Kb of RAM; maximum of two 8" floppy disks; second RS-232 port; 32-bit floating point unit; and a line drawing graphics subsystem." A kinda odd system, with some rather strange limitations for a micro in 1983. Most notably, memory limitations and the fact that there are no hard disks offered for it. Definitely a pre-PC design. I am under he impression that it was originally intended as a word processor, but marketed as a computer. It ran CPM-86 or MS-DOS (both specific to the APC). The graphics board could do 1024 x 1024, although only 640 x 475 could be actually displayed on screen. The color version used an 8 color (3-bit) palette. Suggested base price: Color, dual floppy $4,998 Mono, single floppy $3,298 Jeff On Thu, 18 Nov 1999 09:43:06 -0500 "Charles E.

Amdek Disks and Drives

by Maddog1331＠aol.com

Hey, I was wondering if anyone could give me more info on some stuff. I have bought a HUGE lot of old computer stuff, and part of it is a slew of Amdek disks and disk drives. One of the Amdek drives says Atari computer ( I think...I still have yet to get all this stuff to the house, much less sort through it....gonna be a great weekend of fun :-D) Anyway, whats the deal with Amdek? I have quite a few drives, and a bunch of disks! What was their main purpose? For just Atari, or IBM? Also, what is their capacity? The disks look neat, and rugged...I am hoping that they will still work :-) Anyway, this bunch of stuff came with lots of parts too...sealed keyboard boards for different systems and such. I think that this came out of somebodys old computer repair place. Even has some replacement doohickeys for dot matrix printers. Im still sorting this stuff out. Ill let yall know more as I go along!

I'm estimating you will need at least a 20x20 foot room to run this configuration.

IMHO, an outstanding piece of software. I still use it when I need a quick and dirty solution. Steve Robertson <steverob(a)hotoffice.com>

E.U.N.U.C.H.

by edick＠idcomm.com

4" doesn't really make for a "deep" hole. You should be able to do this with pretty standard drill bits, but cool them and lubricate them. For best results, use a coarse feed and a relatively slow speed with a very sharp (best is freshly sharpened for every hole) tool. Drill your holes in a single stroke, so you won't have to cope with a work-hardened surface. Take your time. If you custom machine your heatsink to fit the enclosure it lives in, fitting it with 1/4" i.d. holes and 1/4" pipe for circulating the liquid coolant (no FREON or other CFC's...we've got to be ozone-layer-friendly) you can always put an arbitrarily large exchanger outside in the winter, to keep the temperature in the circulating fluid somehwere around -100 Celsius. Remember, what matters is the amount of HEAT you transfer, not the temperature difference, though the heat flows faster between regions of more widely differing temperature. You might even find you don't need so large a delta-T. If you move vast quantities of cold air through a 1 cu. yd. outdoor heatsink, you could put an array of large peltier coolers there to heat that heatsink at the expense of the heat carried to it from the computer in the house. Hopefully you're not trying to be terribly efficient . . .

SWTPC 8k Basic / Vintage Software Policy

by doug＠sontek.com

Hello all, I have been watching this list for some time now and have enjoyed the enthusiasm with which people pursue the preservation of the classic machines. My personal project has been restoring a SWTPC 6800 to satisfy my nostalgic needs and I have gotten it up and running solidly. The next step for me in this quest is to locate a copy of the BASIC interpreter I used back then - SWTPC's 8k BASIC. I am willing to take it in any format (i.e. cassette tape, paper listing, disk file, paper tape, ...). Any help along these lines would be greatly appreciated. This brings me to a related second question. What is the consensus on copyright policy for vintage software. I am happy to pay for the software I acquire, but it's obviously more complicated with software written 20+ years ago. Any advice on this would be appreciated and I apologize if this topic has been covered before. Doug Peckham dpeckham(a)ucsd.edu
